DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 3 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a PCB milling cutter processing welding feeding mechanism, comprising a feeding plate 1 installed above a welding chamber seat block 8, a feeding hopper 2 and an L-shaped seat 3 are fixed on the top of the feeding plate 1, a feeding cylinder 4 is installed on the left side of the L-shaped seat 3, a piston rod at the right end of the feeding cylinder 4 penetrates the inner side of the feeding hopper 2, and is fixed with a movable plate 21, a side notch corresponding to the movable plate 21 is opened on the left side surface of the feeding hopper 2, and a feeding port 11 corresponding to the feeding hopper 2 is opened on the bottom surface of the feeding plate 1, and the subsequent operator will pour the PCB milling cutter blank into the feeding hopper 2, and then operate the feeding cylinder 4 , so that the movable plate 21 moves sideways to open the bottom channel of the feed hopper 2, so that the PCB milling cutter blank can fall from the feed port 11 to the lower feed belt to realize feeding. When feeding is not needed, just run the feed cylinder 4 again to reset the movable plate 21 to block the bottom end of the feed hopper 2, and then stop feeding. It also includes a base 5 fixed on the top surface of the welding chamber seat block 8, and a T-shaped shaft seat 6 is fixed on the top surface of the base 5. The left end of the feed plate 1 is rotatably sleeved on the T-shaped shaft seat 6, so that the position of the feed hopper 2 can be adaptively rotated and adjusted, thereby ensuring that the feed port 11 matches the position of the lower feed belt. A limiting structure 7 is also provided between the base 5 and the feed plate 1;

[0019] The limiting structure 7 includes a movable sleeve 76 sleeved on the surface of the base 5, and two limiting rods 77 are symmetrically fixed to the top surface of the movable sleeve 76. The bottom surface of the feed plate 1 is evenly provided with a plurality of limiting grooves 78 corresponding to the limiting rods 77 in an annular array. The limiting rod 77 is inserted into one of the limiting grooves 78 to achieve stable limiting of the feed plate 1 and the feed hopper 2 during daily use, thereby ensuring the stability during feeding. The limiting structure 7 also includes a rectangular inner notch 71 provided on the surface of the base 5, and a vertical rod 73 is fixed at the inner center of the rectangular inner notch 71. The surface of the vertical rod 73 is sleeved with a spring 74 and a sliding sleeve 72. Side connecting rods 75 are fixed on both sides of the sliding sleeve 72, and one end of the side connecting rod 75 extends to The surface of the base 5 is fixed with the movable sleeve 76. If the operator wants to adjust the position of the feed hopper 2 at a later time, he only needs to pull down the movable sleeve 76 to make the side connecting rod 75 move down with the sliding sleeve 72, and compress the spring 74 until the limit rod 77 moves out of the limit groove 78, so that the limit on the feed plate 1 can be released. At this time, the feed plate 1 can be rotated around the T-shaped shaft seat 6, so as to adjust the position of the feed hopper 2 in rotation. When the position of the feed hopper 2 is adjusted to a suitable position, the movable sleeve 76 is released, so that the spring 74 pushes it back and resets it, and the limit rod 77 can be inserted into the limit groove 78 at other positions, so that the feed plate 1 can be limited again, thereby completing the stable limit after the rotation adjustment of the position of the feed hopper 2.

[0020] Among them, a circular hole is opened at the center of the sliding sleeve 72, and the size of the circular hole is adapted to the vertical rod 73, so that the sliding sleeve 72 can slide smoothly on the vertical rod 73, the top of the spring 74 is in tight contact with the bottom surface of the sliding sleeve 72, and the bottom end of the spring 74 is in tight contact with the bottom inner wall of the rectangular inner notch 71, and a circular sleeve hole is opened through the left end surface of the feed plate 1, and the size of the sleeve hole is adapted to the T-shaped shaft seat 6, so that the feed plate 1 can be smoothly sleeved on the T-shaped shaft seat 6 for rotation.

[0023] Specifically, it also includes a disassembly structure 9, which is arranged between the base 5 and the welding chamber seat block 8. The disassembly structure 9 includes an annular socket 91 welded and fixed to the bottom surface of the base 5 and an annular slot 92 opened on the top surface of the welding chamber seat block 8. The annular socket 91 is inserted into the annular slot 92. The disassembly structure 9 also includes a bolt 93 and a nut 94. The bolt 93 transversely penetrates the annular socket 91 and the welding chamber seat block 8 and is fixed by the nut 94, so that the base 5 can be fixed to the welding chamber seat block 8, and it is convenient for disassembly and assembly in the later stage. The surface of the annular socket 91 is symmetrically provided with two through holes corresponding to the bolt 93, and the surface of the welding chamber seat block 8 is transversely penetrated with a through hole 2 corresponding to the bolt 93. The two through holes are for the smooth penetration of the bolt 93, and the through holes are then tightened and fixed by the nut 94.
